The ToolTalk server can be relied upon to broker client and server messages for inter-client plug-and-play. The common object request broker architecture (CORBA) movement has a great deal of strength behind it. But ToolTalk is lightweight, does the job and forms an integral part of CDE, which is deployed across a gamut of Unix platforms. ToolTalk takes message-handling registrations from method servers, then holds that information until client applications broadcast for those registered services. Platform gateways are not needed because ToolTalk interoperates between heterogeneous systems.
There is much more to CDE than meets the eye. Application and workspace developers alike have a rich feature-filled infrastructure upon which to build. Just like in the past, we still rely on the tried and true X and Motif; however, now we can count on the Common Desktop Environment for its development libraries and desktop management infrastructure.
If you are getting ready to write a new application or just thinking about sprucing up something that you have been working on, consider how your application can become more feature rich and desktop friendly with less code.
